Veri kaynağı olarak MySQL tablo verilerini kullanarak bir Google Grafiği oluşturmak için iyi bir örnek bulmak için çok araştırdım. Birkaç gün aradım ve PHP ve MySQL'in bir kombinasyonunu kullanarak bir Google Grafiği (pasta, çubuk, sütun, tablo) oluşturmak için mevcut birkaç örnek olduğunu fark ettim. Sonunda bir örnek çalışmayı başardım.
Daha önce StackOverflow bir sürü yardım aldım, bu yüzden bu sefer bazı dönecektir.
İki örneğim var; biri Ajax kullanır, diğeri kullanmaz. Bugün, sadece Ajax olmayan örneği göstereceğim.
Kullanımı:
Gereksinimler: PHP, Apache ve MySQL
Kurulum:
--- phpMyAdmin kullanarak veritabanı oluşturun ve "chart" olarak adlandırın
--- phpMyAdmin kullanarak bir tablo oluşturun ve "googlechart" olarak adlandırın ve
iki sütun kullandığım için tablonun sadece iki sütunu vardır. Ancak,
isterseniz 2'den fazla sütun kullanabilirsiniz, ancak
bunun için biraz kod yaz
--- Sütun adlarını şu şekilde belirtin: "haftalık_task" ve "yüzde"
--- Tabloya bazı veriler ekleme
--- Yüzde sütunu için yalnızca bir sayı kullanın

Bu soruyu konu dışı olarak kapatmak için oy veriyorum çünkü bu bir soru değil, bir öğretici. Kendisine yanıt verilmez ve rol modelleri yanlış içerik gönderme davranışı göstermez.

mysql_*yeni kodda işlevleri kullanmayın . Artık bakımları yapılmıyor ve resmi olarak kullanımdan kaldırılıyor . Bkz kırmızı kutuyu ? Bunun yerine hazırlanmış ifadeler hakkında bilgi edininve PDO veya MySQLi kullanın - bu makale hangisine karar vermenize yardımcı olacaktır. PDO'yu seçerseniz, burada iyi bir öğretici var .
